I agree with Dibbles, the powder dissolves so easily and is so much less expensive. I either include mine in my lye masterbatch, or dissolve it in a little extra batch water.I’ve never used liquid, but I do dissolve the powdered sorbitol in some of the batch water (I warm it up a bit). I think @AliOop has said she dissolves it in the batch liquid before adding the lye. FWIW, it dissolves easily so if there is a big difference, I’d use the powder.
